Every DeepSeek Harness plugin

What it is — This is a launcher that embeds the DeepSeek Harness Web UI into a standalone Windows desktop window using WebView2, with DeepEye vision and voice input integrated.

Who it is for — Windows users running DSH for graphical tasks who want a standalone window form will find it suitable. People who access DSH via browser do not need this plugin, since the window presentation differs.

Watch out — The portable version is about 180MB including the runtime environment. The slim version is about 256KB but requires Node.js installed. DeepEye vision requires setting up an API key. No obvious issues found.

The verdict — I would install it if I need a standalone window with taskbar icon on Windows, because it decouples the DSH service from window management.

What it is — Displays a short horizontal timeline of user messages on the left side of the conversation in DeepSeek Harness, supporting previews and jumps.

Who it is for — When conducting long conversations in DeepSeek Harness, users who need to quickly locate message positions are suitable for installing this plugin. Users who use short conversations do not need to install this plugin.

Watch out — Sandbox test passed in a new profile, and it was successfully registered by Harness. No obvious issues found.

The verdict — I would install it because it is a pure JS implementation that passed sandbox testing in a new profile.

What it is — Enhances input composer in DeepSeek Harness Web UI with @ for workspace file and directory path insertion and /h menu for current session prompt reuse.

Who it is for — When using DeepSeek Harness for code analysis tasks, quick reference to workspace file paths is needed. If your prompt creation does not use DeepSeek Harness official input triggers for path insertion and prompt reuse, you can skip installing this plugin.

Watch out — From GitHub source installation requires including the built lib/ directory as package entries point to it. Sandbox test passed with installation and registration in a new profile. No other issues found.

The verdict — If frequent workspace path references and session prompt reuse are required in DeepSeek Harness, I would install it because it enhances the official input triggers without overriding core components.

What it is — Adds a draggable 3D liquid-glass floating card to the DeepSeek Harness web GUI for displaying DeepSeek API balance, cumulative spend/token stats across time ranges, adjustable glass/3D/color controls, and one-click top-up.

Who it is for — You monitor DeepSeek API usage in the DSH web GUI and need a floating card for balance and stats display with customizable 3D effects. If your workflow does not involve the DSH web GUI or balance visualization in that format, this plugin is unnecessary.

Watch out — Sandbox testing succeeded: installed into a fresh profile and registered by harness. Executes shell commands for local aggregation. No other issues detected.

The verdict — I would install it to get direct balance and stats in the web GUI, provided that local data processing via shell commands is acceptable.

What it is — Adds a Windows XP Luna desktop theme to the DSH Web UI.

Who it is for — Suitable for users who want to theme the DSH Web UI as a Windows XP Luna desktop. Not suitable for users who do not use the DSH Web UI, because it is a pure browser-side client plugin.

Watch out — Sandbox testing passed: it was successfully installed in a new profile and registered by harness. No obvious issues found.

The verdict — I would install it for the web profile because it provides a Windows XP Luna desktop theme.

What it is — Detects plugin load errors, temporarily skips suspicious plugins, and only restores Boot Guard-managed changes.

Who it is for — When you debug an interface plugin in DSH, the entire Web UI fails to load after refresh, requiring an independent recovery entry to restore the workspace. Those who prefer direct operation in the plugin management page without relying on recovery tools can choose not to install it.

Watch out — Sandbox test passed: installed in a fresh profile and registered by harness into the profile. Configuration changes are executed serially using atomic replacement with temporary files in the same directory, and external changes are checked before committing. It does not delete plugins or touch plugin data.

The verdict — I would install it because it only recognizes Boot Guard's own marks and does not casually clean user configurations.

What it is — Provides two-way Slack messaging for DeepSeek Harness agents over Socket Mode.

Who it is for — If your agent needs to send Slack messages, list channels, receive messages, and reply to threads, install this plugin. If your Slack integration requires a persistent message queue, do not install this plugin.

Watch out — Sandbox test passes, the plugin registers normally in a new profile. The inbox is an in-memory queue that clears on restart. No other obvious issues found.

The verdict — I would install it because sandbox test passes and no public callback is needed, but only if I accept the in-memory queue limitation.

What it is — Ports Remotion skills into DeepSeek Harness for React programmatic video creation.

Who it is for — Users who create videos using React in DSH are suitable to install this plugin. Users who do not use the npm registry are not suitable to install this plugin.

Watch out — Sandbox testing passed: installed in a fresh profile and registered by harness. It will execute shell commands. Rendering requires preparing ffmpeg.

The verdict — I would install it because it supports skills portability across agents.

What it is — Integrates seven ffmpeg-based video processing tools for probing, cutting, concatenating, encoding, subtitling, extracting, and GIF generation.

Who it is for — When your agent needs to process video files in DeepSeek Harness, install this plugin. If your tasks are limited to non-video media files, this plugin is not required.

Watch out — Sandbox testing passed, it can be installed and registered in a new profile. Requires local ffmpeg installation. No obvious issues found.

The verdict — I would install it because it integrates seven video tools with zero runtime dependencies.

What it is — Copy dsh:// session deep links and inject read-only snapshots of referenced sessions into other conversations.

Who it is for — When using DeepSeek Harness Web GUI to handle multiple conversations and need to reference previous session content. Users who only work with single-session tasks without cross-session references.

Watch out — Requires executing shell commands for protocol registration on Windows. Restart Web GUI after installation. No major issues found in sandbox testing.

The verdict — I would not install it unless I frequently reference previous sessions across conversations.

What it is — Integrates PicGo for uploading local images and files to your configured image host.

Who it is for — When Harness agent generates documents or charts with images, the local file link failure issue fits this plugin. Not suitable for users who do not use the /picgo command.

Watch out — Sandbox test passed: installed in a new profile and registered with harness. No obvious issues found.

The verdict — I would install it because it allows the agent to autonomously call the picgo_upload tool, with sandbox test passing.

What it is — Harness UI Enhancer normalizes the official DeepSeek Harness UI and reconciles style conflicts between installed plugins using official design tokens and CSS.

Who it is for — When you have multiple third-party plugins installed causing UI style inconsistencies, this plugin unifies the visual language. If you only use official features without any third-party plugins, you don't need it.

Watch out — Sandbox test passed: installed in a new profile and registered into the profile. No obvious issues found.

The verdict — I would install it because it provides reversible non-invasive UI coordination, but only if unifying visual language across multiple plugins is a priority.

What it is — Integrates the DeepSeek Harness plugin development knowledge base as an on-demand agent skill so the agent can query official constraints, task workflows, API reference and community gotchas while building a plugin.

Who it is for — When building a plugin with DeepSeek Harness, developers who need the agent skill to look up official constraints, task workflows, API reference and community gotchas are suitable to install this plugin. Developers who want to integrate plugin development knowledge through other methods can choose not to rely on this plugin.

Watch out — This plugin will execute shell commands. Sandbox test passed in a fresh profile where it was registered by harness; no obvious issues found.

The verdict — I would install it because it turns the knowledge base into an always-available agent skill for direct lookup during plugin construction.

What it is — dsh-doublecheck installs an engineering discipline guard and delivery gate for DeepSeek Harness.

Who it is for — When an agent needs to implement a vague task in DeepSeek Harness if the task description is unclear and requires confirming the six spec dimensions, it is suitable to install this plugin. If your engineering process does not rely on DeepSeek Harness's skill registry, tool policy pipeline or subagent review, installation is not necessary.

Watch out — Installed successfully in a new profile and registered with Harness. Requires providing an API key or token. Will execute shell commands.

The verdict — I will install it because it converts evidence from the session log into a deliverable/verdict decision, which is valuable for enforcing discipline.

What it is — dsh-permgate is a fine-grained permission gateway plugin for DeepSeek Harness that reviews tool calls by category.

Who it is for — When executing tasks involving external directories or commands, users who need precise control over tool call boundaries are suitable to install this plugin. If you only rely on the platform's preset three permission levels and do not need custom review, you do not need this plugin.

Watch out — Sandbox test passed in fresh profile and registered successfully. Source install from GitHub requires no build script authorization. No obvious issues found.

The verdict — I would install it because it addresses coarse permission granularity in DeepSeek Harness.

What it is — DeepSeek Harness conversation sidebar grid-aligned card workbench with 27 mini-cards including API balance, token usage, and cost estimation.

Who it is for — Users who need to view API balance and token usage during DeepSeek model conversations in DeepSeek Harness would benefit from this. Users primarily working in TUI clients or other non-web platforms would not find this web-based plugin useful.

Watch out — Sandbox test passed: installed in a new profile and registered by Harness into the profile. Installation executes shell commands. No obvious issues discovered.

The verdict — I would install it because it integrates the usage heatmap and image relay cards into the sidebar.

What it is — DeepSeek Harness plugin registers read_graph tool backed by codebase knowledge graph for querying structure, exports, imports and dependencies.

Who it is for — In large codebase maintenance where agents need to quickly answer dependency questions, this is suitable. Users doing only simple text operations can skip it.

Watch out — Sandbox test passed. Will execute shell commands. No other obvious costs found.

The verdict — I would install it because it enables agents to handle code analysis more efficiently, but under the premise that the tool is still in its infancy stage and functionality may change.

What it is — This plugin implements progressive disclosure for DeepSeek Harness tool catalogs through bridge tools, allowing the model to search, describe, and call long-tail tools on demand while keeping core tools eager.

Who it is for — When the tool catalog is large and the model wastes tokens on injecting all schemas every turn, users needing semantic search for long-tail tools via rerank are suitable for this plugin. Users who only rely on eager tools do not need this plugin.

Watch out — Sandbox testing passed, with successful installation and registration into the profile in a fresh environment, no obvious issues found. Configuring a rerank matcher is required to use tool_search.

The verdict — I would install it if token savings for long-tail tools are needed, because it enables dynamic injection through bridge tools.

What it is — This plugin adds a 60-frame theme-aware monochrome whale-dive animation beside the DeepSeek Harness Web turn status, with reactive water and a reduced-motion PNG fallback.

Who it is for — If you use DeepSeek Harness Web for interface development and need to add visual decoration to the turn status area lacking animation, this plugin can be installed. Users not using DeepSeek Harness Web or not wanting turn status decorations do not need to install it.

Watch out — Manual permission for the build script is required when installing from source. Sandbox testing confirmed successful registration in a fresh profile, with no obvious issues found.

The verdict — If turn status decoration with theme-aware animation is required, I would install it because it supports closed-loop playback and clean lifecycle removal.

What it is — Displays a sidebar footer card showing DeepSeek account balance and per-session costs.

Who it is for — Suitable for users conducting model conversations in the DeepSeek Harness web version who need to monitor account balance and session costs. For users not tracking model usage expenses, it is irrelevant.

Watch out — Sandbox test passed. Installed in a new profile and registered by harness. Session cost estimates may differ from actual billing.

The verdict — I would install it because it directly fetches the official balance using the same API key as the model.

What it is — DeepSeek Harness plugin that inserts Auto permission preset, letting classifier auto-approve routine sandbox escalations once.

Who it is for — Suitable for developers handling long tasks and dependency installs who want to reduce manual interruptions with a classifier model. Not suitable for users who want to avoid any human approval, because dangerous operations still require manual review.

Watch out — Tested successfully: installed in fresh profile and registered with harness. Classification calls have timeout that falls back to manual. No obvious issues found.

The verdict — I would install it because it reduces interruptions for routine tasks, but only if you configure a classifier model to avoid timeouts.

What it is — DeepSeek Harness plugin providing bounded cell-addressed read/write for xlsx/pdf/docx/pptx/ipynb formats, plus MCP server and CLI.

Who it is for — Suitable for coding agents using DeepSeek Harness to process Office documents and Jupyter notebooks. If an agent runs in read-only sandbox mode and only needs read operations, this plugin's write capability is not required.

Watch out — Sandbox testing shows it can be installed but the build script is blocked requiring manual permission to register. No other obvious issues found.

The verdict — I would install it because it addresses the limitation of DeepSeek Harness's text-only read, but from-source installation requires manually allowing the build script.

What it is — The dsh-agent-message plugin adds cross-session agent messaging capabilities to DeepSeek Harness.

Who it is for — When operating multiple independent agent sessions on DeepSeek Harness for collaboration, this plugin allows information exchange between them. Users not running multiple agent sessions or not requiring cross-session message passing do not need to install it.

Watch out — The plugin executes shell commands. Sandbox testing passed, registering successfully in a new profile. No obvious issues found.

The verdict — I would install it because it enables direct messaging between agent sessions in multi-session environments.

What it is — dsh-plugin-deepseek-vision is a DeepSeek Harness plugin adding vision analysis capability to text models.

Who it is for — Users needing image analysis with DeepSeek text-only models in DeepSeek Harness. For users of multi-modal models, this plugin is not applicable.

Watch out — The plugin will execute shell commands and requires an API key or token. No obvious issues found.

The verdict — As myself, I would install from source subdirectory because there is no single command for installation.
